Abstract

BACKGROUND

Tumoural calcinosis (TC) is a rare disorder characterized by nonneoplastic amorphous calcium deposition that tends to occur in soft tissues around the large joint. Here, we report a case of cystic TC with ossification and bone marrow formation in the kidney.

CASE PRESENTATION

We report a 63-year-old woman who presented with a complaint of intermittent right lumbar pain for 2 months. Computed tomography (CT) revealed a large cystic lesion on the lateral side of the right kidney, with a circular calcified wall around the lesion, which compressed, deformed and displaced the right kidney. To relieve the symptoms of right lumbar pain, the patient underwent surgical resection of this cystic lesion without partial removal of the renal parenchyma. The pathological results further confirmed the diagnosis of cystic TC with ossification and bone marrow formation in the right kidney. No recurrence was detected 1 year after surgery.

CONCLUSIONS

The main differential diagnoses of TC in the kidney are kidney stone, renal tuberculosis, renal cyst with a calcified wall, and tumour. Patients are treated mainly by complete surgical resection of the lesion.

摘要

背景

肿瘤性钙化（TC）是一种罕见的疾病，其特征为非肿瘤性的无定形钙沉积，常发生于大关节周围的软组织中。本文报道了一例肾脏囊性 TC 伴骨化和骨髓形成的病例。

病例介绍

我们报告了一例 63 岁女性患者，因间歇性右侧腰痛 2 个月就诊。计算机断层扫描（CT）显示右侧肾脏外侧有一个大的囊性病变，病变周围有圆形钙化壁，压迫、变形并移位右侧肾脏。为缓解右侧腰痛症状，患者接受了该囊性病变的手术切除，未行部分肾实质切除。病理结果进一步证实了右侧肾脏囊性 TC 伴骨化和骨髓形成的诊断。术后 1 年无复发。
